Über Mohamed

Full-Stack Software Engineer with 4+ years of experience designing and building microservices-based applications in production environments. I specialize in backend development using Java and Spring Boot, with strong expertise in RESTful API design, Backend-for-Frontend (BFF) architectures, and scalable system design for mobile and web applications.

I have contributed to complex projects at Capgemini, Valtech Mobility, and CLAAS 365FarmNet, where I worked on refactoring legacy systems, developing new backend features, and improving system performance, stability, and maintainability. My work includes implementing CI/CD pipelines, applying Test-Driven Development (TDD) to reduce regressions, and integrating secure authentication and authorization solutions.

On the frontend, I have hands-on experience with Vue.js and React.js, enabling effective collaboration across full-stack teams and ensuring well-aligned API and UI design. I am comfortable working in Agile environments, participating in cross-team architectural discussions, and representing teams in Communities of Practice.

I communicate fluently in Arabic, German, and English, which allows me to collaborate effectively in international and cross-functional teams. I value clean code, pragmatic solutions, and continuous learning, and I enjoy tackling technically challenging problems that have real user impact.

Looking for: Backend-focused or full-stack roles where I can contribute to scalable architectures, high-quality systems, and teams that care about engineering excellence.
